Tenant Rights and Obligations in Switzerland: Tenancy Law Guide

Swiss tenancy law: what every tenant needs to know

Tenancy law in Switzerland is governed by Articles 253 to 274g of the Code of Obligations (CO) and the Ordinance on the Lease and Tenancy of Residential and Commercial Premises (OBLF). It is a dense but essential area of law for every tenant, especially during a move.

Whether you wish to terminate your lease, contest a rent increase, sublet your flat or simply know your rights in the event of a dispute, this guide provides all the information you need, updated for 2026.

Lease termination by the tenant

The basics

In Switzerland, the tenant may terminate their lease subject to the following conditions:

• Notice period: generally 3 months for a residential property (some contracts provide for a longer period — check your lease)
• Termination date: the notice must coincide with an official termination date stipulated in the contract
• Form: by registered letter, received by the landlord no later than the last day of the month preceding the start of the notice period
• Signature: if the lease is in the name of two persons (married couple or registered partners), both must sign the termination letter

Official termination dates by canton

The dates vary by canton and lease agreement. Here are the most common:

Important: always check your lease agreement, as it may provide for different dates and notice periods from cantonal custom.

Early termination (outside the official date)

If you need to leave your property before the official termination date, you may do so provided you present a replacement tenant who is:

• Solvent (no debt enforcement proceedings, sufficient income)
• Acceptable to the landlord (objective criteria)
• Willing to take over the lease on the same terms

The landlord cannot refuse a replacement tenant without legitimate reason (Art. 264 CO). If the replacement is accepted or if the landlord refuses without valid reason, you are released from your obligations as soon as the replacement could reasonably take over the lease.

Practical advice:

• Propose at least 1 to 2 solvent candidates
• Make the proposal in writing (registered letter)
• Allow a reasonable period before the desired departure date (in practice, at least 30 days)

Lease transfer

A lease transfer allows you to assign your lease to a third party without termination. This is a useful option in certain cases (moving abroad, change in family circumstances).

• The landlord must consent to the transfer (Art. 263 CO)
• They may only refuse for a legitimate reason
• The new tenant must be solvent and the lease must be taken over on the same terms
• The former tenant remains jointly liable for the rent for a maximum of 2 years after the transfer

Subletting

Legal conditions (Art. 262 CO)

The tenant has the right to sublet all or part of their property, but must obtain the prior consent of the landlord. The landlord may only refuse in three cases:

1. The tenant refuses to disclose the terms of the sublet
2. The terms are unfair compared to the main lease (excessive sub-rent)
3. The sublet causes a major inconvenience to the landlord

Practical rules

• Inform the landlord in writing before subletting, specifying: the identity of the sub-tenant, duration and rent charged
• The sub-rent must not be significantly higher than the main rent (a reasonable margin is accepted for furnished accommodation)
• Subletting via Airbnb is increasingly regulated in Switzerland. Several cantons and municipalities impose restrictions (mandatory declaration, maximum duration, tourist tax)
• The tenant remains responsible to the landlord even when subletting

Property defects

Types of defects

Swiss law distinguishes three categories of defects:

Procedure in the event of a defect

1. Report the defect in writing to the landlord or property manager (registered letter with photos)
2. Set a reasonable deadline for the repair (7 to 30 days depending on the severity)
3. If the landlord does not respond within the given period:
   • Request a proportional rent reduction
   • Deposit the rent with the relevant authority (Art. 259g CO)
   • Have the repair carried out by a third party at the landlord’s expense (for urgent cases)
   • Terminate the lease with immediate effect (only for serious defects that remain unrepaired)

Minor repairs at the tenant’s expense

The tenant must bear the cost of routine minor repairs according to local practice. In practice, this concerns repairs costing less than approximately 150-200 CHF:

• Replacing a tap washer
• Changing light bulbs
• Unblocking a trap
• Replacing an extractor filter
• Lubricating a lock or hinge

Rent increases and challenges

Rent increases

The landlord may increase the rent in the following cases:

• Rise in the reference mortgage rate (published quarterly by the Federal Housing Office, currently at 1.75% in early 2026)
• Increase in maintenance costs (Swiss consumer price index)
• Value-enhancing works (improvements, major renovations)
• Adjustment to the usual rent for the area or locality

The increase must be notified on an official form (form approved by the canton) with 10 days’ notice before the next termination deadline.

Challenging an increase

The tenant may challenge a rent increase they consider unfair:

• Deadline: 30 days after receiving the increase notice
• Body: conciliation board of the relevant district
• Grounds: rent higher than comparable rents in the area, excessive landlord return, increase disproportionate to the rise in costs
• Procedure: free before the conciliation board
• If conciliation fails, the tenant has 30 days to take the matter to court

Initial rent

When concluding a new lease, the tenant may challenge the initial rent if they consider it unfair (Art. 270 CO):

• Deadline: 30 days after taking possession of the property
• Conditions: the tenant must have been compelled to conclude the lease by personal or family necessity, or the rent must have increased significantly compared to the previous tenant
• In cantons where the official form is mandatory at the conclusion of the lease, the tenant must have received disclosure of the previous rent

Protection against unfair eviction

When is an eviction unfair?

The landlord may terminate the lease, but the eviction is considered unfair (voidable) in the following cases (Art. 271 and 271a CO):

• To force the tenant to buy the property
• Because the tenant asserts in good faith claims arising from the lease (for example, a repair request)
• During conciliation proceedings or ongoing court proceedings related to the lease (unless the tenant acted in bad faith)
• Within 3 years of the end of lease-related proceedings in which the landlord lost
• Due to a change in the tenant’s family situation (marriage, birth, etc.)

How to challenge an eviction

1. Apply to the conciliation board within 30 days of receiving the eviction notice
2. The board attempts a conciliation between the parties
3. If this fails, the tenant has 30 days to take the matter to court
4. The court may annul the eviction if it is unfair, or grant a lease extension (up to 4 years for residential premises, 6 years for commercial premises)

Lease extension

Even if the eviction is valid, the tenant may request a lease extension if the termination would cause hardship for them or their family:

• First extension: up to 4 years for residential premises
• Second extension: possible, maximum total duration of 4 years
• The extension is granted by the court or agreed in conciliation
• The rent may be adjusted to market conditions during the extension

The conciliation board

The tenancy conciliation board is a free, joint body that acts as the mandatory first step for any lease-related dispute.

Jurisdiction

• Rent challenges (initial, increases)
• Unfair eviction and lease extension
• Property defects
• Return of the rental deposit
• Property inspections and repairs
• Any dispute between landlord and tenant

Procedure

• Application: by written form addressed to the district conciliation board
• Deadline: varies by type of dispute (30 days for eviction or increase)
• Cost: free (no fee)
• Hearing: both parties are summoned for a conciliation attempt
• If conciliation succeeds: an agreement is signed and has the force of a judgment
• If it fails: authorisation to proceed is issued; the tenant may take the matter to court within 30 days

Tenant obligations

During the lease

• Pay rent and charges on time (generally in advance, at the start of the month)
• Use the property with care and respect the house rules
• Report immediately any defects requiring urgent repair
• Tolerate necessary maintenance and renovation works
• Do not modify the property without the landlord’s consent (major drilling, painting in colour, changing flooring)
• Respect the neighbours (noise, municipal quiet hours)
• Maintain the property with care (minor repairs, regular cleaning)

At the end of the lease

• Return the property in the condition in which it was received, subject to normal wear and tear
• Carry out end-of-lease cleaning — see our end-of-lease cleaning guide
• Attend the exit property inspection — see our property inspection guide
• Return all keys (including copies)
• Repair damage beyond normal wear and tear — see our property handover guide

The rental deposit

Amount and form

• Maximum 3 months’ rent (Art. 257e CO)
• Deposited in a guarantee account in the tenant’s name at a Swiss bank
• The landlord may not freely access this sum
• Alternative: surety through a specialist organisation (SmartCaution, firstcaution, goCaution) — annual cost of approximately 5% of the guaranteed amount

Return of the deposit

• If no claims are raised at the exit inspection, the deposit should be released promptly
• The landlord has a maximum of 12 months to assert claims after the property is returned
• If the landlord withholds the deposit without reason, the tenant may apply to the conciliation board
• Interest accrued on the guarantee account belongs to the tenant
